ADOLF MARTINI AND FRITZ DEIMEL, OF BERLIN, GERMANY, ASSIGNORS TO SAID MARTINI.

GAS-IGNITION APPARATUS.

SPECIFICATION forming part of Letters Patent No. 619,200, dated February '7, 1899.

Application filed September 25, 1897. Serial No. 652,970. (No model.)

To aZZ whom it may concern.-

Be it known that we, ADOLF MARTINI, acitizen of the United States, and FRITZ DEIMEL, asubject of the German Emperor, both residingin Berlin, Germany, have invented certain new and useful Improvements in Gas-Ignitin g Apparatus, of which the following is a speci fication.

Our invention relates to gas-igniting apparatus, utilized more particularly in connection with hydrogen gas, coal-gas, or any gaseous mixtures to ignite the same either for illuminating purposes or in connection with gasengines; and the object of the invention is to provide a means which moves the igniting device automatically into the path of travel of the gas when not ignited and retires it when ignited.

In carrying our invention into effect we make use of the known property of finelydivided platinum to ignite a jet of coal-gas or any other inflammable gaseous matter directed on it and of a device for either bringing a pill or globule of said platinum into the direction of the gas-jet to be ignited or swinging it out of its way when it has been ignited.

In the drawings, Figure 1 is a front elevation of a chimney or gas-cylinder, illustrating our improved igniting apparatus in operative position thereon. Fig. 2 is a plan view of the same.

' l designates a chimney or gas-cylinder of a burner for illuminating purposes or connected with an engine using gas as a motive power, to which is secured a rim 2, encircling the upper edge of the same. Secured to and projecting upwardly from the rim 2 is a bracket 3, which carries a horizontal arm 4 upon its upper end, the outer free end thereof projecting over the chimney or cylinder, as shown. Carried by the rim 2 at a point beneath the arm 4, but at one side of the same, is a bearing 5, in which fits and revolves the lower end of an inclined spindle 6, the upper end of said spindle having a bearingin the free end of the arm 4. Secured upon said spindle 6 at a point directly beneath the arm 4 is a fan-wheel 7, the blades 8 of which incline, as shown, one edge of the wheel projecting over the chimney. The current of air produced in the chimney when the flame is burning is able to rotate the described fan.

Carried by the wheel 7 upon the outer edge of one of its blades is a socket or clamp 9, in which is secured the pill 10, containing powdered platinum, the weight of the socket or clamp and of the platinum acting as a weight to normally hold the latter over the cylinder.

Secured to and depending from the arm 4 at 11 is a projection 12, which projects into the path of travel of a corrugation 12 upon one of the wheel-blades, said projection being located contiguous to the socket or clamp 9, whereby when the wheel is revolved in the direction of the arrow, Fig. 1, due to. the force of the gas impinging upon the wheel, the wheel is caught by the catch and held from revolution by the catch supplemented by the force of the gas, and consequently is out of the path of travel of the gas.

In operation, the parts being in the position shown in Fig. 1 in full lines and gas being turned on andadmitted to the chimney, the gas rises and impinges upon the platinum pill, which ignites the gas. The current of hot air also impinges upon the wheel and revolves the same, causing the spongy platinum to assume the position shown in dotted lines, Fig. 1. When the action of the stream of hot air ceases, the wheel resumes its normal position by gravitation.

It will readily be seen that our invention broadly consists in means for intermittently projecting a platinum pill into or out of the path of travel of the gas, the latter movement being due to the movement of said gas.

What we claim is- 1. In a gas-igniting apparatus a fan or vane wheel with inclined blades, journaled over the burner, and having its axis slightly inclined; and a pill of finely-divided platinum or any similar material fixed to the fan, substantially as'shown and described.

2. In a gas-igniting apparatus a fan with inclined blades journaled over the burner, a pill of finely-divided platinum or the like carried by the fan, and a stop for limiting the movement of said fan.

In witness whereof We have hereunto signed our names in the presence of two subscribing witnesses.
